LOCKING AND RELEASING DEVICE FOR, BOAT-TACKLES.

Application filed January 6, 1919.

To all whom it may concern:

Be it known that I, Gnnnrr HILGERs, a subject of the Queen of theNetherlands, residing at Rotterdam, Province of South Holland, in theKingdom of the Netherlands, have invented certain new and usefulImprovements in or Relating to Locking and Releasing Devices forBoat-Tackles, of which the following is a specification.

This invention relates to locking and releasing devices for boattackles.

It is important, that-boats, while being lowered re released from thefalls exactly at the right moment and it is desirable, that not onlythis releasing takes place at the exact moment, but that both falls, bymeans of which the boat is suspended are released simultaneously.

According to the invention both tackles are loosened simultaneously byasingle manipulation. The choice of the exact moment must of course beleft to the operator of the device, consequently to one man only.

According to the invention the arrangement consists of twolocking-bolts, rotary mounted on fixed trunnions from which bolts theboat is suspended by means of the falls. The bolts abut with a bevelededge in such a way against the also beveled faces of the closing-rodswhich are rotary mounted on two-fixed trunnions and connected with eachother by means of a coupling rod, that the closing members have atendency to swing and to release the locking device under the influenceof the strain on the bolts.

One of the closing rods is provided with an extension provided with ahandle, which in the locking-position of the bolts can be fastened.

The invention is hereinafter described with reference to theaccompanying drawmg.

Figure 1 shows a longitudinal section of a boat with my locking andreleasing device; and Fig. 2 shows the mechanism ofthe device on alarger scale.

The tackle-blocks engage the horizontal locking-bolts 3 and 4 by meansof a hook or eye 1 and 2. The locking-bolts are rotary mounted on thetrunnions 5 and 6, fixed to the stationary bolts 7 and 8 or the likesecured to the bottom of the boat A. The locking-bolts 3 and 4 arebeveled at their front ends so asto form an inclined face 9, 10.

The bolts being locked, these inclined faces Specification of LettersPatent.

Serial No. 269,881.

abut with the also inclined faces of the closing-rods 11 and 12, whichare rotatably mounted on the fixed trunnions 1S and 14 secured to thebottom of the boat. The closing-rods 11 and 12 are connected by means ofa connecting rod 15, pivoted to the said closing-rods 11 and 12.

The weight of the boat and crew suspending from the bolts 3 and 4, willtend to swing the rods 11 and 12 about the trunnions 13 and 14, underthe influence of the beveled faces, 9 and 10; in the drawing the rods 11and 12 tend to swing to the left. One of the rods is provided with anextension carrying a handle, which can be fastened in some suitablemanner f. i. by means of a pin or in the way of the brake-levers ofmotor-cars.

The device can be rapidly applied to a boat and occupies but littlespace when applied, the handle 16 only extending sufficiently high to beeasily operated.

As in these arrangements the operation of the handle does not requireany exertion of power, but on the contrary the said handle always has atendency to move, the pulling over of the handle on the precise momentand therefore the releasing of the falls is always guaranteed.

By regulating the inclination of the faces 9 and 10 and placing thebeveled edge of the closing-rods more or less close to the trunnions13and 14, the pressure exerted on the said rods can be regulated.

What I claim is:

1. A locking and releasing device for boats, comprising two pivotedlocking bolts with which the falls suspending the boat are adapted toengage, said bolts having their free ends beveled, two pivoted closingrods having beveled faces with which the beveled ends of the lockingbolts engage, one of the rods being extended to form a handle, and a rodconnecting the closing rods.

*2. A locking and releasing device for boats, comprising two pivotedbolts with which the falls suspending a boat are adapted to engage, twopivoted members. one forming a handle and with each of which the freeend of a bolt has locking engagement, and a link connection between thesaid members.

In testimony whereof I have hereunto set my hand.

GERRIT HILGERS.
